idescat_list_statistics

List available statistics from IDESCAT when search results are too broad or empty. Use the returned statistics_id to drill down with idescat_list_nodes.

Instructions

Browse fallback when idescat_search_tables is too broad or empty. Start here, then call idescat_list_nodes with a returned statistics_id.

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, and the description does not disclose any behavioral traits such as side effects, rate limits, or auth requirements. It only states the purpose, failing to add transparency beyond that.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with key purpose and usage, no extraneous information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having an output schema, the description lacks parameter explanations and does not cover the full context needed to use the tool independently. It only covers the high-level workflow.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description does not explain any of the three parameters (lang, limit, offset). Agent gets no guidance on their meaning or effect beyond the schema's type/enum definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states 'Browse fallback when idescat_search_tables is too broad or empty', specifying the action (browse) and resource (statistics), and distinguishes from sibling tools by positioning it as a fallback and part of a workflow with idescat_list_nodes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says when to use ('when idescat_search_tables is too broad or empty'), and what to do after ('call idescat_list_nodes with a returned statistics_id'), providing a clear usage flow and alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
